Overview of the Routers
Cisco Integrated Services Routers Generation 2 (ISR G2) offer data functionality through Gigabit Ethernet ports and security functionality with a virtual private network (VPN) accelerator on the motherboard. Additional security features are available with add-on hardware and software.
Cisco 2900 series and Cisco 3900 series routers also provide voice IP telephony with digital signal processor (DSP) capability; and voice gateway, DSP farm, IP-to-IP gateway, Cisco Unified Communications Manager Express (CUCME) via Cisco IOS. Cisco Unity Express (CUE) is provided through the use of add-on hardware.
This series of ISRs have new slots that support next generation Enhanced High-Speed WAN Interface Cards (EHWICs), Internal Services Modules (ISMs), Packet Voice Data Modules (PVDM3s), Service Modules (SMs), and Services Performance Engines (SPEs).
Access to the Cisco Multi-Gigabit Fabric (MGF) facilitates connection between switch ports on the ISR without utilizing all of the external ports. A logical GE interface on the ISR connects external and internal modules through the MGF for improved LAN and WAN switching.

Locating the Serial Number, PID, VID and CLEI
Software License
To obtain a software license, you need a product authorization key (PAK) and the unique device identifier (UDI) of the device where the license will be installed.
The serial number (SN), product ID (PID), version ID (VID), and Common Language Equipment Identifier (CLEI) are printed on a label on the back of the router or on a label tray located on the router chassis or motherboard. The UDI can be viewed using the show license udi command in privileged Exec mode in Cisco Internet Operating System (IOS) software. For additional information on the UDI or how to obtain a PAK, see the Cisco Software Activation on Integrated Services Routers document at Cisco.com.
The UDI has two main components:

Gigabit Ethernet Ports
There are two different types of Gigabit Ethernet (GE) ports available on Cisco 2900 series and Cisco 3900 series ISRs.
GE Ports
The GE RJ-45 copper interface ports support 10BASE-T, 100BASE-TX, and 1000BASE-T.
SFP Ports
The small-form-factor pluggable (SFP) ports support 1000BASE-LX/LH, 1000BASE-SX, 1000BASE-ZX, and Coarse Wavelength-Division Multiplexing (CWDM-8) modules, as well as 100Mbs SFP modules.
The SFP port shares the same physical port as an RJ-45 GE port. Table 1-4 shows the models that support SFP installation. The SFP port supports auto-media-detection, auto-failover and remote fault indication (RFI), as described in the IEEE 802.3ah specification.
Use the media-type {rj45{auto-failover}} | {sfp{auto-failover}} command to enable the auto-media-detection and auto-failover features. Use the Command Lookup Tool for details about this command.
The SFP port can be configured for the following behaviors:•
•
•
•
USB Serial Console Port
The Mini-USB type B serial port has been enabled to perform management tasks on the router. To use this port, you must install a Windows USB device driver before establishing physical connectivity between a personal computer and the router. See the "Installing the Cisco Microsoft Windows USB Device Driver" section for driver installation instructions.
Removable and Interchangeable Modules and Cards
Table 1-5 summarizes the type of removable modules and cards that can be installed in the router to provide specific capabilities. Services Performance Engines (SPEs), Service Modules (SMs), and Enhanced High-Speed WAN Interface Cards (EHWICs) fit into external slots and can be removed or replaced without opening the chassis.
Internal Services Modules (ISMs), expansion DRAM memory modules and next-generation Packet Voice Data Modules (PVDM3s) plug into internal connectors inside the chassis. These modules can be removed and installed only by opening the chassis on the Cisco 3900 series, or sliding the motherboard out of the Cisco 3900 series.
External Slots
•
Internal Slots
Because of physical differences with the new slots, legacy network modules and legacy Service Modules require an adapter for installation.
WarningSee the Overview of Cisco Network Modules and Service Modules for Cisco Access Routers document for general information and single- and double-wide slot numbering.
See the Installing Cisco Network Modules in Cisco Access Routers document for instructions that describe how to install SMs, legacy network modules, and legacy Service Modules in the router.
See the Overview of Cisco Interface Cards for Cisco Access Routers for general interface card information.
See the Installing Cisco Interface Cards in Cisco Access Routers document, for instructions that describe how to install EHWICs and legacy interface cards in the router.
Note
Table 1-5 shows the number of internal and external slots on Cisco 2900 series and Cisco 3900 series ISRs. It also shows the number of EHWICs and SMs that are supported in the router slots at any time. Table 1-8 shows memory specifications by router.

2 EHWIC slots support HWICs, WICs and VICs.
3 AIMs are not supported.
4 PVDM3 slots support the installation of PVDM2 modules with an appropriate adapter. PVDM2s can not be intermixed with PVDM3s. See the Hardware Installation Guide for router.
Services Performance Engine
Services Performance Engines (SPEs) are modular motherboards for Cisco 3900 series ISRs. The SPE includes PVDM3 slots and system memory slots, and the ISM slot. The Services Performance Engine provides a modular approach to system upgrades. Slide out the SPE from the router to replace internal modules, or to upgrade the SPE for improved router performance.
See the "Removing and Replacing the Services Performance Engine" procedure for installation information.
Table 1-6 lists four SPE models that are supported on Cisco 3900 series routers. SPEs illustrations are shown in the "Chassis Views" section. SPEs come preinstalled in 3900 series routers, or they are purchased separately and installed in a 3900 series router. See the support table for more information.

Note
Service Modules
Service Modules (SM) are the largest modules on Cisco 2900 series and Cisco 3900 series ISRs. With the largest form-factor and power capacity, these modules deliver high-performance service applications. SMs are physically larger than legacy network modules, as a result, network modules require an adapter for installation. See the Installing Cisco Network Modules in Cisco Access Routers guide for installation instructions, http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/InstNetM.html.
Enhanced High-Speed WAN Interface Cards
Enhanced High-Speed WAN Interface Card (EHWICs) are the latest generation of interface cards. EHWICs are installed in the EHWIC slot on the router. Legacy interface cards, such as WAN interface cards (WICs), voice interface cards (VICs), high-speed WAN interface cards (HWICs), double-width high-speed WAN interface cards (DHWICs), and (EHWICs) are supported in the EHWIC slot on the router.
Services Performance Engine 200 and Services Performance Engine 250 support the following legacy interface cards in the EHWIC slots. (See Table 1-7.)
Table 1-7
EHWIC Support for SPE 200 and SPE 250
Integrated Service Modules
Internal Services Modules (ISM) supersede advanced integration modules (AIM) on Cisco 2900 series and Cisco 3900 series ISRs. The ISM is larger in size than the AIM. Due to these physical differences, the AIM does not fit into the ISM slot and is no longer supported on Cisco 2900 series and Cisco 3900 series ISRs.
Packet Voice Data Modules
The Packet Voice Data Modules (PVDM3s) are the latest generation of PVDMs. First-generation PVDM-I cards are not supported in the PVDM3 slots. Due to physical differences, PVDM2s require an adapter for installation in the PVDM3 slot. See the "Installing and Removing PVDM2s" section for installation instructions.
Note
Memory
Cisco 2900 series and Cisco 3900 series routers contain the following types of memory:
•
Note
•
•
Note
Table 1-8 summarizes the memory options for Cisco 2900 series and Cisco 3900 series routers. Default memory represents the minimum usable RAM. You can install additional RAM up to the maximum amount.
Expansion memory modules are UDIMMs or VLP RDIMMs with error correction code (ECC). All onboard RAM uses ECC.
Note
Power Supplies
Cisco 2900 series and Cisco 3900 series ISRs support a variety of power supply configurations. All power supplies are field replaceable and externally accessible with the exception of the Cisco 2901 ISR. The Cisco 2901 ISR has an internal power supply, which requires removing the cover for replacement.
If configured with dual power supplies or an Redundant power supplies (RPS), the power supplies are hot swappable. RPSs require an RPS adapter. There are two versions of the RPS adapter, one for the Cisco 2911 and one for the Cisco 2921 and 2951. Both use the Cisco Redundant Power System 2300.
Configurations include AC and DC (with and without IP), Dual DC, internal POE, and POE boost.

5 Uses Cisco Redundant Power System 2300 as 100% power boost. Internal power supply does not supply any boost. In this configuration there is no POE redundancy.
Module and Router Power Consumption
Cisco 2900 series and Cisco 3900 series ISRs have energy efficiency features that reduce power consumption. Some of the energy efficiency features are controlled by the hardware, whereas other energy efficiency features are controlled by the software.
Hardware Features
•
Software Features
•
Fans, Ventilation, and Airflow
The Cisco 2911 and Cisco 3900 series ISRs have optional fan filters that are easy to replace. The filters may be used to meet Network Equipment Building Systems (NEBS) requirements, or to operate in dusty environments. When a filter becomes dirty, discard it and replace it with a new one. See the "Replacing a Fan Tray or Air Filter" section.
Fan speeds are controlled by the fan speed controller circuitry. To minimize noise, the fans operate at one of several predetermined speeds and are dependent on the input ambient air temperature.

Real-Time Clock
Upon system power up, the internal real-time clock with battery backup provides the system software with the time of day. This allows the system to verify the validity of the certification authority (CA) certificate. The Cisco 2900 and Cisco 3900 series routers have a lithium battery. This battery lasts for the life time of the router under the operating environmental conditions specified for the router and is not field-replaceable.
Note
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Secure Key
A hardware secure key storage unit is provided on the Cisco 3925 and Cisco 3945 routers to safely store passwords and credentials. The secure key storage unit is a self-contained tamper-resistant computer key-store that acts as a black box for credential storage by accepting credentials and never returning them.
Cryptographic Accelerator
Cisco 3925E and Cisco 3945E ISRs ship with a Services Performance Engine that includes an onboard cryptographic accelerator. It shares security processing for SSLVPN and IPSec. By default, acceleration of SSL is disabled so IPSec performance is maximized.
If you want to set up the router as an SSLVPN gateway, enable the SSLVPN feature with the
crypto engine accelerator bandwidth-allocation ssl fair command. To learn more about the cryptographic accelerator, see the Configuring the Security Features module in the Cisco 3900 series, 2900 series, and 1900 series Integrated Services Routers Software Configuration Guide at Cisco.com.Slot, Port, and Interface Information
Table 1-11 and Table 1-12 show slot, port, and interface numbering ranges.
On the Cisco 2901 router, the numbering format for slots and ports is defined as follows: interface type 0/slot/port. "0" indicates slots that are built into the chassis of a router. On the Cisco 2901 router, all slots begin with "0," because all slots are built into the chassis. On the Cisco 2911, 2921, 2951, and Cisco 3900 series routers, some slots are built into the chassis and some are external.
Slots that are part of a network module or an extension voice module have numbers that begin with "1" or "2," respectively. See the module documentation for more information.

1 On the Cisco 2901 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an asynchronous interface, use the interface number to specify the async line. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0 on a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.
2 Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
3 Applies only to Cisco 3945 and Cisco 3945E routers.
4 Applies only to Cisco 2921 router.

Periodic Inspection and Cleaning
Periodic inspection and cleaning of the external surface of the router is recommended to minimize the negative impact of environmental dust or debris. The frequency of inspection and cleaning is dependent upon the severity of the environmental conditions, but a minimum of every six months is recommended. Cleaning involves vacuuming of router air intake and exhaust vents and replacement of air filters. See the "Fans, Ventilation, and Airflow" section and the "Replacing a Fan Tray or Air Filter" section.
